So you just want people's souls to escape out their noses? You're a monster.

I am actually on the complete opposite end of this and I consider it rude not to say something. It fits into other manners like "please" and "thank you".

It's such an arbitrary relic. I don't know if people ever really believed saying something helped the soul or whatever, but it's so tedious. Or people get competitive and try to be that person, who's polite and then it sets the standard of good manners.

At least if you're gonna acknowledge I sneezed, could you give the person a tissue? At least then you'd be doing something.

And don't even get me started on the chud types who explicitly say 'god bless you' like every sneeze is a battlefield in the culture war

I like saying something when I sneeze. Like "gadzoontypes!"
